Problems solved by technology

[0004] In the prior art, CFD is based on VLAN applications, but CFD does not provide support for dynamic VLAN registration protocols; in addition, CFD configuration is extremely complex, when there are many domains and MEPs (MaintenanceassociationEndPoint, maintenance endpoints), it is necessary to go to each device More configurations are performed on the Internet, the configuration workload is very heavy, and the implementation is extremely inflexible

Embodiment Construction

[0057] GVRP (GARP (GenericAttributeRegistrationProtocol, Generic Attribute Registration Protocol) VLANRegistrationProtocol, GARPVLAN Registration Protocol) is used to register and cancel VLAN attributes. Such as figure 2 As shown in , it is a schematic diagram of the application scenario of the GVRP network, and the process of opening up the dynamic VLAN actually includes the following process:

[0058] Statically configure VLAN100 on device A, add P1 port to VLAN100, and send a Join message carrying VLAN100 through P1 port; after receiving the Join message, P2 port of device B learns dynamic VLAN100, adds P2 port to VLAN100, The port sends a Join message carrying VLAN100; the P2 port of device C learns dynamic VLAN100 after receiving the Join message, adds the P2 port to VLAN100, and sends the Join message carrying VLAN100 through the P1 port; the P2 port of device D receives the Join message Learn the dynamic VLAN100 after the article, add the P2 port to VLAN100, and send ...

Abstract

The invention discloses a method and a device for realizing CFD (Connectivity Fault Detection) based on a dynamic VLAN (Virtual Local Area Network) registration protocol. The method for realizing CFD based on the dynamic VLAN registration protocol includes steps that an Active Speaker device transmits a Join message carrying CFD configuration parameters to a Passive Speaker device through a Passive device; the Passive device inherits the first line of CFD configuration of the CFD configuration parameters from the Join message, deletes the first line of the CFD configuration of the CFD configuration parameters from the Join message and continues to transmit the Join message to the Passive Speaker device; the above steps are repeated until the Join message is transmitted to the Passive Speaker device and the Passive Speaker device inherits the first line of the CFD configuration of the CFD configuration parameters from the Join message; and the Active Speaker device realizes CFD by utilizing a received implicit CCM message. According to the invention, the CFD configuration can be delivered to different devices through a dynamic VLAN.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a CFD (Connectivity Fault Detection, connectivity error detection) implementation method and device based on a dynamic VLAN (Virtual Local Area Network, virtual local area network) registration protocol. Background technique [0002] CFD is a VLAN-based end-to-end OAM (Operations, Administration and Maintenance) mechanism in the Layer 2 network. It is mainly used to detect link connectivity, confirm faults, and determine the location of faults in the Layer 2 network. In the CFD network, MD (MaintenanceDomain, maintenance domain) refers to a network or a part of the network covered by connectivity error detection. The concept of level (level) is introduced in MD. MD is divided into eight levels, with integers from 0 to 7 means that the larger the number, the higher the level, and the wider the range of MDs; different MDs can be adjacent or nested, but cannot cross, ...
